Most importantly: which JDK/JRE are you running WebLogic under? And which weblogic version do you use?
You have definitely checked diskfree? (df -h) and mem is also no concern? Are you running a 32 or 64 bit JVM? Under 32 bit JVMs you could easily run out of available threads (the higher you tune your -Xmx, the LOWER the amount of available threads get!) Just a few random ideas...
