# Apache::Symdump(3pm)

Symbol table snapshots

## NAME

Apache::Symdump - Symbol table snapshots

## SYNOPSIS

```
 PerlLogHandler Apache::Symdump
```

## DESCRIPTION

Apache:Symdump uses Devel::Symdump to record snapshots of the Perl symbol table in ServerRoot/logs/symdump.$$.$n Where **$$** is the process id and **$n** is incremented each time the handler is run.  The **diff** utility can be used to compare snapshots and get an idea of what might be making a process grow.  Normally, new symbols come from  modules or scripts that were not preloaded, the Perl method cache, etc.

```
 % diff -u symdump.$$.0 symdump.$$.1
```

## CAVEATS

Apache::Symdump does not cleanup up its snapshot files, do so simply by:

```
 % rm logs/symdump.* logs/incdump.*
```
