Urban Novak commented on JENKINS-13814:
---------------------------------------
There are several ways to deal with this issue
- disable changelog calculation
- configure jenkins use 64-bit JVM with maximum heap size 2 GB or more
- split CVS repository to several smaller ones
> java.lang.OutOfMemoryError exception when getting the remote log

> Some notes:
> - The path/ and path\ comes from the "Remote Name"/"Local Name" settings
> solution from Issue JENKINS-13264
> - We are using Jenkins 1.464 with the 2.4-SNAPSHOT version of the CVS plugin,
> but may not have been caused by this specific version
> - The arguments setting in the jenkins.xml file currently has -Xms1024m
> (anything larger and Jenkins service won't start)
> - The CVS module has many legacy projects spread out, and thus, contains more
> than 7,000 directories and many more files
> - Things had worked with the 1.6 plug-in & CVSNT client, but it also
> occasionally timed out getting the changelog, hence our testing of the 2.x
> plug-ins
