Apache Errors and Page Cannot be Displayed

[otrsfan3000]

I'm having a problem where agents will randomly receive a "Page Cannot be displayed" whether they are creating new tickets, updating an existing ticket or closing a ticket. According the the eventvwr entry (id1000 Application Error) it is related to perl512.dll.
This is the eventvwr entry:

Code: Select all

Faulting application httpd.exe, version 2.2.19.0, faulting module perl512.dll, version 0.0.0.0, fault address 0x0001cd33.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

This is what the apache logs say:

Code: Select all

Another error I see is:

The other thing I notice is a constant "Scalars leaked: 1" All of these errors have been happening since OTRS (3.0.11) was installed and it is running on Windows Server 2003 R2 SP2 using the windows installer. Everything is running off of this one server, Apache as well as mysql. Is there anything that can be done? In other similar threads I've seen suggestions to upgrade to a newer version of OTRS but I'm nervous that might introduce more problems than solve them. At first agents didn't get "Page cannot be displayed" as often but its gotten progressively worse.

i looked in to your problem and lots of people blame libmysql.dll.
