I'm running apache 1.3.4 on Redhat 5.1 with JServ 1.0b2, JDK1.1.7v1a and TYA1.2v3 and getting the following error in the apache error log file: E0608 Unexpected result from mutex.4 TYA:Signal 11 in doWork Anyone know what could cause this? It was running just fine before (on a solaris box). Thank you, Joel Shellman knOcean Interactive http://corp.knocean.com/
