Processing a Core Dump File
If a system crash occurs on the Cisco PGW 2200 Softswitch, the system might generate core dump files,
which are stored in the $BASEDIR/var directory. You can review the core dump files as part of the
diagnosis process, to determine what caused the system to crash. The system periodically searches the
$BASEDIR/var directory for core dump files.
When the system identifies a core dump file, it performs the following steps:
• Determines which executable dumped the core.
• Finds the current time of the system.
• Renames the core dump file, inserting the executable that dumped the core and the date and time
that the file was identified, using the following format:
core.execname_yyyymmddhhmms
For example, if the failover daemon process (foverd) dumped the core on August 17, 2001 at
12:29:37, the core dump file is named as follows:
core.foverd_20010817122937
• Raises a crash information collected alarm.
Note The process manager processes the core dump file when it receives a signal from a failed child process.
If the process manager dumps the core file, it does not perform the preceding steps.
