Dan Berindei commented on ISPN-4033:
------------------------------------

The timeout error seems to be caused by very long GC pauses:

{noformat}
[16:31:20] :		 [org.infinispan:infinispan-core] 490.847: [GC490.848: [ParNew (promotion failed): 95104K->95104K(95104K), 14.8925940 secs]505.740: [CMS506.524: [CMS-concurrent-sweep: 0.902/15.823 secs] [Times: user=19.15 sys=6.03, real=15.82 secs] 
[16:31:22] :		 [org.infinispan:infinispan-core]  (concurrent mode failure): 812577K->317912K(838912K), 3.2331000 secs] 869638K->317912K(934016K), [CMS Perm : 48980K->48757K(80104K)], 18.1268550 secs] [Times: user=20.99 sys=5.90, real=18.12 secs]

The pause seems excessive for just 300MB, so it could have something to do with the OS1 machine the build is running on. Changing the collector to G1 looks promising, with maximum pauses of about 2 seconds, but that's still a little high so I'm trying to see if it can avoid Full GCs completely.
