Applet crashing abruptly

I am using applet in my application. Now I am noticing that randomly applet is getting crashed. There is no specific point where it crashes, or specific operation after which it crashed.
After crash it generates an hs_err_pid..log file at the desktop. It mentions the following stuff :
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION (0xc0000005) occurred at PC=0x80750C5
Function=[Unknown.]
Library=C:\PROGRA~1\Java\J2RE14~1.2_0\bin\client\jvm.dll

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.

Now one common thing I have noticed during all crashes is that perm gen is 99% or 98% at the time of crash (see the last line in above log).
Does that mean the perm gen is less or some other problem is there? And if memory at all is the reason, why am I getting EXCEPTION_ACCESS_VIOLATION and not some error of type OUT_OF_MEMORY_EXCEPTION ?

Thanks in anticipation
