Tracing Function Calls in a program
Apart from writing debug and statements in constructors is there any way by which we can trace the function call stack at any depth?

The issue that we always face is that when program crashes (Web Server running on Linux) we have no idea where it crashes and we have to do the hard way of debugging.

Is there any library / extra code that we can include and that can output the function flow in a program given a scenario.

Sorry I tired a lot of programs but without extra debugging (followed by compilation) we are not sure where the code flows. If it gives us the line number that would be more perfect.

Thanks in advance

flow-expire

flow-expire(1)						      General Commands Manual						    flow-expire(1)

NAME

       flow-expire -- Manage storage of flow file archives by expiring old data.

SYNOPSIS

       flow-expire [-h]  [-d debug_level]  [-e expire_count]  [-E expire_size] -w workdir

DESCRIPTION

       The flow-expire utility will remove the oldest flow files in a directory based on either a count of files or space utilization.	The direc-
       tory is recursively searched for flow files.  Files that do not have a flow-tools signature will be ignored.   The  internal  timestamp	is
       used  so backups or copies of the flow files that do not retain the original timestamp will not impact the operation of flow-expire.  flow-
       expire is typically used to manage storage in a distributed environment where flows are collected on  a	different  server  than  they  are
       archived.

OPTIONS

       -d debug_level
		 Enable debugging.

       -e expire_count
		 Retain the maximum number of files so that the total file count is less than expire_count.

       -E expire_size
		 Retain the maximum number of files so that the total storage is less than expire_size.  The letters b,K,M,G can be used as multi-
		 pliers, ie 16 Megabytes is 16M.

       -h	 Display help.

       -w workdir
		 Work in workdir.

EXAMPLES

       Remove the oldest flow files in /flows/krc4 until the total storage is less then 2 Gigabytes.

	 flow-expire -E2Gig -w /flows/krc4

       Remove the oldest flow files in /flows/krc4 until the total number of files is less then 100.

	 flow-expire -e100 -w /flows/krc4

BUGS

       Empty directories are not removed.
