Allocation Failure in std_server0.out log

[Former Member]

can anyone decipher if there is an issue or if this is normal java GC?

Thanks

John

Hi,

When do you get this error. Is the J2ee engine running or not? Give more details.

Usually you don't have to take care of the GC output there as long as you don't have memory leaks. The output is used for performance statistics and traces.
