Cos now after examining the server log, I saw an error : The reference to entity "ampUseLegacyDatetimeCode" must end with the ';' delimiter.)

Mark Hello Mark, Thanks for your reply and thanks for your last reply about the changing the xml file in which I havn't thank you cos I was grappling with so many things... I just found out that this guy he is using some kind of 'embedded Tomcat' to do the work I am not very sure though. And so I was trying to edit an external Tomcat server thus it never works. I am quite new to the way it was done cos eventually I found it inside apache-tomcat inside the AppData !

Re: insufficient memory for the Java Runtime Environment to continue
If you use large heaps you should use G1 garbage collector And if you use that then I would set the min and Max to the same values *-server -Xms13G -Xmx13G **-XX:+UseG1GC* *To fully initialize the memory at once (g1 will figure it into compartments)* Op za 22 dec. 2018 13:35 schreef Dhaval Jaiswal I am facing issue of crashing JAVA process and log files attached for the > same. > > Server total RAM is 16 GB. > > catalina.sh having following setting. > export JAVA_MEM_OPTS="-Xms1g -Xmx15g -XX:MaxPermSize=1536m" > > Can some one help where could be the problem?

Re: insufficient memory for the Java Runtime Environment to continue
Application built in such a way that it consum memory and hence, it's exhaust all memory and results in crashing Java. Probably GC is not running when it reaches to its threshold. Is there a way I can call GC explicitly without affecting running application. I believe need to identify the memory consumption as well.

Adding to John's question, what I forgot earlier: Another rule of thumb is to identify the *minimum* amount of memory that the application can run with, then add a bit of headroom.

Which threads are > consuming memory. How can i get rid out of this issue. In addition to all the other great answers you already got: I've made it a principle to configure production systems with identical values for -Xms and -Xmx. In the end I'm intending to provide the max memory anyways, and if something goes wrong along the way (as it does for you in this situation) I prefer to know of the problems right when I start up the server - not Sunday night at 3am when it tries to allocate the missing (and allowed) chunk of memory from the OS before failing. Experimenting along this principle will help you to quickly figure out how much memory your system actually can provide (be aware of the required non-heap memory that Christopher mentioned, when forming your expectations.

There's also non-heap ("native") memory, too, which isn't limited. If
I had server with 16GiB RAM I wouldn't think of getting anywhere near
a 14GiB heap.

How's this for an update to the EncryptInterceptor documentation: " If using the TcpFailureDetector, the EncryptInterceptor must be inserted into the interceptor chain before the TcpFailureDetector.

A zero-byte file won't be decrypted properly. (BTW this explains why I got a BadPaddingException in that *single* test... I forgot that the test decrypts the file left-behind from the previous test. This was intentional, to ensure that there wasn't some magical state being held within the JVM allowing it to decrypt the message.) > and it deletes the message.bin file and the subsequent 2 tests > can't find it.

No. The tests are running as expected. > Also, I tried just using the exact encryptionKey128 you had within > the test class and that one didn't work in my config either, same > BadPaddingException. Try running the test twice in a row. From your output, it looks like the test runs fine. Oh, you meant using my cafebabe key in your setup didn't work? Please see Keiichi's reply: it seems that the EncryptInterceptor must be "outside" of the TcpFailureDetector. - -chris -BEGIN PGP SIGNATURE- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlwebM8ACgkQHPApP6U8 pFg2ew/+K1IqiZQR7brZVz7Oi8wa7VdRWvVz8viQDrTj05dbRCdicntdxz7PTWXQ SGNH/qxXaPfgDHq2N7S8zDHwpj0gTfadn6IFuWUgZYR3jaufpEAS4lmNpyg8e5K4 +JIacYRZDGaMWzGo+MvhNLPZQ/RhdMc2MMHW6Gmg4PSU7vwYP6o3Pp5TZsOd7U6p asQKKDfleVjavxeLUOVlUoXwxXIGdYBe8Jd0iuS725xG68GX//8az85nHkbJfrqd 0jgKx2YpWONStGjOtlsNhBEn9Sj5XTdZ3qJV36O1KtfT1vYBFZtzD748iuLTS+GI xxcVZuxdZgbF2qrISnPCfjnGVC0lJn6mDJgXMdVNCJ//kqlsrq1BTu5elOgRZxsG dLNF5WqVdPpBzFnHXaTg1nLxK0/wtox6RVR6ENid5jto6vu+nX5M+Fnus02st5W0 7OsKkODnz8Vc32tB1u6HwvfQiVvEYU/kTQhMG6Crvouqzguzl4rjH9A3rLzYugSs 5bULs57Ac6d+xnp/8lwM0742piCJD60oBHEYqLWDZQjYPc0sIo77bzBceJXk3t4K tIPZuOJOaQVBTom/CThoWMmliaECD7QL9dJnci2Rr4G8QBL+Bw86vvDOej/HnW6b N5A1brToQjHJQ7M2DeKm/u+mT0xG8zBgGAI0VL6DK229yOLpvFo= =nSuF -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: insufficient memory for the Java Runtime Environment to continue
You should provide at least Java version. Out of the blue you should have at least 2Gb for the OS, so if your server is having 16 Gb, your Xmx and MaxPermSize shouldn't be more then 14 G TOGETHER. Of course this only applies to versions of java below 1.8, because there is no permspace in modern jvms anymore (called metaspace now) and in this case this setting doesn't do anything. Still, you should reduce Xmx to 13 or less.

insufficient memory for the Java Runtime Environment to continue
I am facing issue of crashing JAVA process and log files attached for the same. Server total RAM is 16 GB. catalina.sh having following setting. export JAVA_MEM_OPTS="-Xms1g -Xmx15g -XX:MaxPermSize=1536m" Can some one help where could be the problem? Which threads are consuming memory. How can i get rid out of this issue. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Tomcat Manager keeps asking for Authentication
I am running Netbean 8.2 and am trying to study a web project from github. It was stated that certain pages are constrained by the Tomcat Role, in order to view the Admin panel. So, what I did was to alter the Tomcat C:\Program Files\Apache Software Foundation\Apache Tomcat 8.0.27\conf\tomcat-user.xml And here's what I added: Error message : Deployment error: Access to Tomcat server has not been authorized. Set the correct username and password with the "manager-script" role in the Tomcat customizer in the Server Manager. See the server log for details. I also tried below but it can't work also. Here's the constraint that is imposed at the web.xml under WEB/INF: -- You can restrict access to admin pages by uncommenting the code below--> administrator of the website administrator Admin Login /admin_panel/* /admin/* administrator BASIC Admin Login --> Please let me know what I have done wrong.
