Hi,
We have an application on RHEL4 U4 which uses JNI calls.
During endurance, it fails after about 10 laks of message syaing the following
*** glibc detected *** double free or corruption (!prev): 0x094019e0 ***
bt of the core shows the following
(gdb) bt
#0 0x0021d7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
#1 0x002857a5 in raise () from /lib/tls/libc.so.6

#11 0x00000000 in ?? ()
We tried to troubleshoot this issue by ensuring the build options, linker options etc. We have revisited the code for malloc/free but could not solve it
Kernel : 2.6.9-42.ELsmp
glibc : glibc-2.3.4-2.25
gcc : 3.4.6
We have been trying with valgrind but surprisingly the following options could not generating any log:
algrind --tool=memcheck --log-file=valgrind.output --num-callers=20 --leak-check=yes --trace-children=yes java xxxxxxxxxxxxxxxxx
Any known issues ? with these versions of glibc/gcc.When browsed many ppl have posted the same issue but no proper resolution.Any help would be appreciated
Thanks inadvance
