Package: libc6 Version: 2.7-18 Severity: normal I am getting a segfault or segabort & stacktrace in apache error logs while invoking custom module by apache2-mpm-prefork with php5. *** glibc detected *** /usr/sbin/apache2: malloc(): memory corruption: 0x0847b468 *** ======= Backtrace: ========= /lib/libc.so.6[0xb7d9a845] /lib/libc.so.6[0xb7d9cde2] /lib/libc.so.6(__libc_malloc+0x96)[0xb7d9e586] /lib/libc.so.6[0xb7d8b4ff] /lib/libc.so.6(fopen+0x2c)[0xb7d8b5cc] /lib/libnss_files.so.2[0xb6d9aa80] /lib/libnss_files.so.2(_nss_files_getprotobyname_r+0x37)[0xb6d9b067] /lib/libc.so.6(getprotobyname_r+0xa2)[0xb7e12302] /lib/libc.so.6(getprotobyname+0x77)[0xb7e12197] /usr/lib/php5/20060613+lfs/mrl.dll(mlSndRcv+0x1e3)[0xb60f6d93] /usr/lib/php5/20060613+lfs/mrl.dll(__call_mrldll+0x556)[0xb60e4558]
It looks like it is triggered by getprotobyname or libnss... Also, it is not easily reproducible, i.e. it happens occasionally, 4-5 times a day on a busy server.
