This is a potential fix for the Timeout Problem from BUG "JBCACHE-1592". This
Patch fix The Problem by removing the line:
"ctx.getOptionOverrides().setLockAcquisitionTimeout(0);" in the
"org.jboss.cache.interceptors.MVCCLockingInterceptor.java" in line 202.
This line set the Timeout to zero and deranges the System to gain a Lock.
Removing this line prevents this.
Patch is in the attached file.
