JVM crash while memcpy during class load

My JVM crashed the and the hs_err file showed that it crashed while attempting to load a class. Specifically while trying to memcpy ([libc.so.6+0x6aa2c] memcpy+0x1c). I looked at the .class file and was able to determine what class was being loaded. But can any one tell me what could cause this or how i could determine more about the cause? If the JVM was out of memory wouldn't it throw an Error. Any insight is greatly appreciated. I've included an excerpt from my hs_err file. ``` # # An unexpected error has been detected by Java Runtime Environment: # # SIGBUS (0x7) at pc=0x005aba2c, pid=20841, tid=2427227056 # # Java VM: Java HotSpot(TM) Client VM (1.6.0_02-b05 mixed mode) # Problematic frame: # C [libc.so.6+0x6aa2c] memcpy+0x1c # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # --------------- T H R E A D --------------- Current thread (0x90d0dc00): JavaThread "ORDERHANDLER" [_thread_in_native, id=20881] siginfo:si_signo=7, si_errno=0, si_code=2, si_addr=0x915e3000 Registers: EAX=0x91218298, EBX=0xb7f2e71c, ECX=0x0000079b, EDX=0x915dfef2 ESP=0x90ac6a34, EBP=0x90ac6a60, ESI=0x915e2ffd, EDI=0x914f0a0d EIP=0x005aba2c, CR2=0x915e3000, EFLAGS=0x00010206 Top of Stack: (sp=0x90ac6a34) 0x90ac6a34: b7f29d4b 914ed930 915dff20 00004f49 0x90ac6a44: 082e7bc4 00006f6f 00004243 00004f49 0x90ac6a54: b7f2e71c 080e3e54 00000000 90ac6a90 0x90ac6a64: b7f29fbb 080e3b00 080e3e54 00000000 0x90ac6a74: 00000000 90d0dc00 00000000 d68dd1b6 0x90ac6a84: b7f2e71c 90ac6ad8 90d0dcec 90ac6f00 0x90ac6a94: b7f21169 080e3b00 90ac6ad8 0000002b 0x90ac6aa4: 0000002b 90ac6ad8 00000008 00000000 Instructions: (pc=0x005aba2c) 0x005aba1c: 8b 74 24 08 fc d1 e9 73 01 a4 d1 e9 73 02 66 a5 0x005aba2c: f3 a5 89 c7 89 d6 8b 44 24 04 c3 90 90 90 90 90 Stack: [0x90a78000,0x90ac9000), sp=0x90ac6a34, free space=314k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libc.so.6+0x6aa2c] memcpy+0x1c C [libzip.so+0xbfbb] ZIP_GetEntry+0x10b C [libzip.so+0x3169] Java_java_util_zip_ZipFile_getEntry+0xc9 J java.util.zip.ZipFile.getEntry(JLjava/lang/String;Z)J J java.util.zip.ZipFile.getEntry(Ljava/lang/String;)Ljava/util/zip/ZipEntry;
