Re: [OpenBD] Re: Help figuring out why openbd stops working

['Alan Holden' via Open BlueDragon]

I think your OpenBD app needs more memory allocated. Exception in thread "Timer-0" java.lang.OutOfMemoryError: unable to create new native thread     at java.lang.Thread.start0(Native Method)     at java.lang.Thread.start(Thread.java:691)     at org.aw20.util.SystemClock.setTime(SystemClock.java:132)     at org.aw20.util.SystemClock.access$000(SystemClock.java:29)     at org.aw20.util.SystemClock$1.run(SystemClock.java:61) ... and so on... IMHO - It's not that "CronPluginThread" is the cause of the problem. It's the victim of the problem. It runs every x (even after the rest of your app has crashed for whatever reason), so your log is filling up with those cries for help. Memory usage is displayed in the OpenBD administrator settings page, and is allocated according to some JVM settings. You can search on "tomcat webapps memory allocation" specific to your platform and version.

If I let it wait a long time it does eventually time out, but it takes a few minutes. I thought it might have been Tomcat crashing, but I can go to the Tomcat UI and look at the server status.  Memory use is usually only around 50% of available memory. I thought MySQL crashed, but I can use the same website URL and go to the phpmyadmin page, and MySQL Responds, showing the data. I thought Apache crashed, but I can go to other websites that are not Coldfusion based. I thought maybe the Server Memory was exhausted, but it is usually no more then 75% in use. I thought Server load maybe the issue, but it never reaches above .34 - .5 The crash generally happens after OpenBD has been running for atleast 24 hours, but once in a while it occurs within an hour. I went to /opt/openbd/bluedragon/work/temp/rtelogs folder and looked at the records need the time of crash, but there is nothing out of the ordinary.  And what I mean is OpenBD cannot find something due to a blank variable or an typo. Ex: Type Database Query Error Table 'crossingtheveil.Selena_Stonetype' doesn't exist Datasource CROSSINGTHEVEIL Native Error Code 1146 SQL State 42S02 SQL SELECT ID, read_type, description, time_space, per_minute, cost, used, toolID FROM Selena_Stonetype WHERE active = 1 Tag Context CFQUERY (/home/crossingtheveil/public_html/scheduler/landing.cfm, Line=29, Column=9) | +-- CFIF (/home/crossingtheveil/public_html/scheduler/landing.cfm, Line=10, Column=2)     |     +-- CFELSE (/home/crossingtheveil/public_html/scheduler/landing.cfm, Line=9, Column=1)         |         +-- CFIF (/home/crossingtheveil/public_html/scheduler/landing.cfm, Line=7, Column=1) Source 26: </cfif> 27: <cfset thisType = "#Session.MM_SeerURL#type"> 28: <cfset thisList = "#Session.MM_SeerURL#list"> 29: <cfquery name="q_session" datasource="#Session.dbsource#" username="#Session.dbuname#" password="#Session.dbpass#"> 30: SELECT ID, read_type, description, time_space, per_minute, cost, used, toolID ^ Snippet from underlying CFML source I also was digging around Tomcast and Catalina log files. I am attaching several log files from tomcat/logs directory.  I think I have the issue in the Catalina OUT file.  But I am not sure how to stop that as I am not using CF Crontab functions.

I have looked into the temp files and have not seen any errors that say anything about running out of memory. -- -- online documentation: http://openbd.org/manual/ http://groups.google.com/group/openbd?hl=en --- You received this message because you are subscribed to the Google Groups "Open BlueDragon" group.
