java - GCTaskThread JVM Crash -

-

my jvm (7.0_21-b11) crashing randomly (sometimes after 1 day , sometime after 1 month). using api makes jni calls. based on quick search seems happens either because of faulty jni calls or faulty ram / disk. running tests , enabled -xcheck:jni can eliminate both of above point.

are there other reasons can cause jvm crash in these circumstances.

these top few lines hs_err_pid log file. 

**# jre version: 7.0_21-b11 # java vm: java hotspot(tm) 64-bit server vm (23.21-b01 mixed mode windows-amd64 ) # problematic frame: # v  [jvm.dll+0x31e6ec] # # core dump written. default location: c:\app\bin\hs_err_pid9099.mdmp ---------------  t h r e d  --------------- current thread (0x0000000001cdc000):  gctaskthread [stack: 0x0000000000000000,0x0000000000000000] [id=90672] siginfo: exceptioncode=0xc0000005, reading address 0x0000000000000220**

you using old version of java jdk7 update 21. crash occured in gc. gc issue caused bug corrupts heap memory. issue gc, compiler, bad native code. without reproducer hard debug. have specif test case can reproduce issue, possibly there solution. suggested solution upgrade java version
