Hi guys,
just curious if any have had or tried to resolve a seg fault with gmond.
It appears to be happening in or just after the pthread call.
I have some ltrace output for those who might be able to assist in
this..
OS: Redhat AS3 latest release with updates
Kernel: 2.4.23 compiled static from kernel.org
gcc: Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit

Thread model: posix
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-24)
Here is the last few lines from ltrace where the seg fault is occurring
