JVM (64-bit 1.5.0._22), crash on GCTaskThread

One of our development servers is constantly crashing and the reports look very similar. We think this is due to lack of memory, but we want to check it. Could you guys help in this process? Below you will find the relevant information from the hs_err file.

Thank! Yon

Out of memory should not cause JVM crashes. If so, this is a JVM error, and the only real fix for the JVM error is the update.

The only possibilities I can imagine where this is “your mistake”:

  • - - , ,

  • JVM ,

  • .

, , GC . , .

- , JVM- ( ). JVM ( ), ... BIG- Oracle .

, perm gen "-XX: PermSize = 256m -XX: MaxPermSize = 256m". , .

gc gc.
