[Geoserver-users] Possible deadlock issue in jai.util.SunCachedTile.hashKey

GeoServer GeoServer User
1

Hello everyone,

We have noticed a strange issue when running Geoserver. Every now and then the server announces:

'INFO: Maximum number of threads (200) created for connector with address null and port 8080'

After this all requests hang and eventually time out. The stack trace of the server in this non-functional state is pasted below. The interesting part seems to be the thread # 198:

"http-8090-198" - Thread t@anonymised.com
    java.lang.Thread.State: RUNNABLE
         at com.sun.media.jai.util.SunCachedTile.hashKey(SunCachedTile.java:107)
         at com.sun.media.jai.util.SunTileCache.getTiles(SunTileCache.java:477)
         - locked <2f160844> (a com.sun.media.jai.util.SunTileCache)

The mutex in SunTileCache is locked by this thread and apparently never released, which causes other working threads to block and the server to become unresponsive. Whether or not this is a true deadlock remains a question, but the server nevertheless becomes unresponsive. Any input would be highly appreciated.

Sincerely,
Tuomo Lauri

The Geoserver is running on RHEL 6.4 with Sun Java runtime version 1.6.0_45-b06. The Geoserver instance is as follows:
