Logback should have complained about the unknown property. Anyway, let

My experience with file locks on NFS is "use at your own risk". Some NFS implementations are better than others. If you must log to a single file I would recommend writing to a socket and then have a single process write to the file. Although many people here seem to have no problems, in the data center I work on we ran into this years ago and don't allow it anymore.

Re: Prudent [sic!] mode logging to NFS-mounted file

We recently (within the last few months) decided to try prudent mode on an
NFS mounted file system. We saw apparent deadlocks but in reality it ended up being a bug in the Solaris NFS code (non java) that made the locks very slow (not deadlocked). It was on Solaris 10.x x86. Oracle identified it as a bug and came back with a patch, but we had since given up on NFS locking. If you're familiar with C and running commands like "truss", you might also want to verify NFS locking support with java and logback out of the picture. I can send a test C program if desired. -casey On 12/28/11 3:19 PM, "ThomasSchuessler2@..." <ThomasSchuessler2@...> wrote: We are getting stuck threads, any advice? ####<Dec 28, 2011 9:29:30 AM EST> <Error> <WebLogicServer> <[obfuscated]> <soa_server1> <[STANDBY] ExecuteThread: '395' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <8f08ad23754ca371:-6015b447:13484e5a335:-7ffe-0000000000005269> <1325082570435> <BEA-000337> <[STUCK] ExecuteThread: '261' for queue: 'weblogic.kernel.Default (self-tuning)' has been busy for "707" seconds working on the request "weblogic.servlet.internal.ServletRequestImpl@429fb0e6[ POST /Custom[obfuscated]Service/Custom[obfuscated]Port HTTP/1.1 TE: trailers, deflate, gzip, compress User-Agent: Oracle HTTPClient Version 10h SOAPAction: "null" Authorization: [obfuscated] Accept-Encoding: gzip, x-gzip, compress, x-compress ECID-Context: 1.a161c6d66e04e744:-2716b1b5:1346c7f4437:-7ffe-00000000000a19aa;kXhDsLK[ obfuscated]KIVPToLQSJLQSqPRO_GNRmKS Content-type: text/xml; charset=UTF-8 Content-Length: 3607 Connection: Keep-Alive Proxy-Client-IP: [obfuscated] X-Forwarded-For: [obfuscated] X-WebLogic-KeepAliveSecs: 30 X-WebLogic-Force-JVMID: unset X-WebLogic-Request-ClusterInfo: true ]", which is more than the configured time (StuckThreadMaxTime) of "600" seconds.
