[infinispan-dev] AsyncCacheWriter is dead

[Andreas Kruthoff]

Hi dev


I'm running infinispan-7.0.1 (will soon upgrade to 7.0.2).

I've configured 2 distributed caches, both are similar.

Example cache1:
...
<distributed-cache name="infinicache-lbd-imei" mode="SYNC"
async-marshalling="false" owners="2"
     l1-lifespan="600000" l1-cleanup-interval="60000" statistics="false">
   <eviction strategy="LIRS" max-entries="20000000"/>
   <expiration max-idle="86400000" interval="30000"/>
   <persistence passivation="true">
     <file-store
         path="/data1/infini-lbd"
         preload="true" shared="true" purge="false">
       <write-behind/>
     </file-store>
   </persistence>
</distributed-cache>
...

Today, I've seen that one of the two caches suddenly doesn't exist
anymore somehow (JMX access to numberOfEntries returns nothing?!).

After looking into the application logfile, I've found this:

2014-11-19 13:45:47,310 ERROR
[AsyncStoreCoordinator-infinicache-lbd-imei] AsyncCacheWriter.java:267
ISPN000055: Unexpected error in AsyncStoreCoordinator thread.

         at java.lang.Thread.run(Thread.java:745) ~[na:1.7.0_72]



No error before nor after this entry. It looks like it's related to
<write-behind/> to me, so I'll remove that setting.

But I'd like to write asynchronously for best performance.

Any help would be appreciated!
