Critical We are experiencing an issue with our Jenkins servers (multiple) crashing sporadically throughout the day. Initially, there was thought that it could be a JDK version issue and went through with updating the JDK on our servers, however this did not solve the issue.
Attached are the following four log files produced by the jvm:
- log1.txt and log2.txt are before the JDK update from two of our servers
- hs_err.txt (Jenkins v. 1.651.1) and hs_err2.txt (Jenkins v. 1.580.3) are after the JDK update from two of our servers
[JENKINS-39388] Sporadic Jenkins Crashing Across Different Servers
log1.txt and log2.txt were collected before Java upgrade. hs_err.txt and hs_err2.txt were collected after Java upgrade.
OpenJDK Runtime Environment (7.0_111-b01) (build 1.7.0_111-mockbuild_2016_07_22_09_37-b00).....taken from hs_err2.txt.

OpenJDK Runtime Environment (7.0_111-b01) (build 1.7.0_111-mockbuild_2016_07_22_09_37-b00).....taken from hs_err2.txt. carvac2 do you run Jenkins within TomCat?
If yes, https://github.com/java-native-access/jna/issues/678 seems to be very similar.

Both reported servers use ancient version of Java 7: "
vm_info: OpenJDK 64-Bit Server VM (23.2-b09) for linux-amd64 JRE (1.7.0_09-icedtea-mockbuild_2013_01_15_04_12-b00), built on Jan 15 2013 04:17:45 by "mockbuild" with gcc 4.4.6 20120305 (Red Hat 4.4.6-4)". Has this log been collected before or after Java upgrade?
