Hi
Thank you
I do have the same behaviour if I set Xms/Xmx in the Java Option or if I set
the Initial and Maximum memory pool (I removed Xms/Xmx from Java Option for
that test)
I really think it would be interesting if you could test on a Win 2019 with
32Gb of RAM as I would think you should be able to reproduce since I have had
several reports of this issue now.
Thank you
Kind regards
Christophe

Xms/Xmx
Hi
As additional information I have done further testing
Windows 2016 32Gb RAM
Xms/Xmx 20g
Pagefile 5g
Service restart works fine
Same configuration on Windows 2019, restart fails with mentioned memory issue.
Windows 2019 8gb RAM
Xms/Xmx 7g
Pagefile 2g
Restart works fine
So it seems to happen only on Windows 2019 with larger heap size.
Note that this was reported to me by others, so it appears to be easily
reproducible .
I wonder if you would have a chance to test on a Windows 2019 , 64 bit Build
17763 (10.0.17763.2686) with above mentionned configuration as I feel you
would reproduce.
Thank you
Kind regards
Christophe

Hi Chris
Thank you for the information, this is interesting indeed.
Yes, I am using the default service installed by Tomcat installer so using
procrun and tomcat9.exe
I have tried adding -DCATALINA_OPTS="-Xms20g -Xmx20g" under the Java Options
parameters in tomcat9w.exe > Java tab But this is not taken into account
When I google this, it seems we can't set CATALINA_OPTS when starting as a
service
Do you have further details on how to set CATALINA_OPTS when starting a service
?
Thank you
Kind regards
Christophe

Hi
Thank you for your answers,
Here below is the output of system part of hs_err file.
Note though If I execute a manual stop and manual start immediately after, this
work, no issue.
It is only when I use the Restart option.
Both tests are done one after the other, so the overall amount of memory used
on the machine at the time is the same in both cases.
When the service stops the committed memory goes down to 2.4 Gb, as nothing
else is running on that machine, so there is plenty memory left to restart the
process, which indeed happen when we use Stop then Start, but not with Restart.
I have spent some time with Microsoft too as I thought it was due to the OS,
but they are telling me it is not and it is related to Tomcat.
I have a process dump that they help me collect. They mentioned it should be
helpful to you to check with the symbols.
Let me know if you are interested about it.
Thank you
Christophe

Subject: Tomcat service does not restart on Windows with high value of Xms/Xmx
Hi
I am using Tomcat 9.0.52 and 9.0.60 on Windows server 2019 version 1809 (OS
Build 17763.2686) The machine has 32Gb of Ram Pagefile size 4Gb The Tomcat
service is configured with Xms20g Xmx20g added in the Java 8 parameters I am
using Amazon corretto 11.0.14
Everything works fine if using Stop / Start in Control Panel > Services However
if the service is already started and I select Restart, then it stops the
service but fails to start with
error 1067: The process terminated unexpectedly.
Hs-err.pid file is created with OutOfMemoryError and:
There is insufficient memory for the Java Runtime Environment to continue.
Native memory allocation (mmap) failed to map 21474836480 bytes for Failed to
commit area from 0x0000000300000000 to 0x0000000800000000 of length 21474836480.
If setting Xms and Xmx to 16Gb, it works.
If the pagefile size is increased to 32Gb, then it works also However we should
not need that pagefile as when Tomcat is stopped, only 2.5Gb out of the 32Gb
are used, and it works just fine if we do the 2 step process of Stop and then
Start.
Using other application, Zookeeper, does not show this problem, the restart
works ok even when set to 20Gb, so it seems something with the Tomcat service
management.
Any help will be appreciated
Thank you
Chris
