Java EXCEPTION_ACCESS_VIOLATION - strictly a JVM issue? Nothing on my part? -

this message not long seems - attached lengthy log report @ end

hi all,

i running experimental crawler implemented in java. recently, after 36 hours operation, jvm crashed issuing exception access violation log file. read lot file, still little cryptic me. here relevant "stack" version inside generated log file:

stack: [0x0000000033270000,0x0000000033370000],  sp=0x000000003336f8b0,  free space=1022k native frames: (j=compiled java code, j=interpreted, vv=vm code, c=native code) v  [jvm.dll+0x138998] v  [jvm.dll+0x3f238a] v  [jvm.dll+0x3efa30] v  [jvm.dll+0x3ecfbe] v  [jvm.dll+0x299f7a] c  [msvcr100.dll+0x21d9f] c  [msvcr100.dll+0x21e3b] c  [kernel32.dll+0x159ed] c  [ntdll.dll+0x2c541] 

as can see, @ least log file, error did not start java code, ntdll library, instructions execution reached exception @ jvm [edit: or maybe other way around? ended ntdll?]. do not want dismiss "well... i'll reinstall jvm , windows , maybe it'll work" (though i'd that), try see if there's can it. known issue or fixes can applied, other obvious ones stated. problem error occured after on 36 hours, it's hard reproduce.

also need invoking

system.gc(); 

every 8 seconds make sure memory cleared. if matters in anyway.\

i not using graphics libraries.

i not using jni code.

thanks lot reading , possibly helping,

amir.
