Hello,

This issue seems to be an exact replication of the following thread and the
said solution of the case sensitive drive letter does not fix it for me.

http://osgeo-org.1560.x6.nabble.com/MS4W-3-0-4-dev-MapCache-Crash-td4647812.html

I have not tried installing this in the C:/ drive yet. Might give it a go
if I cannot find anything else. Currently its on the D drive. Also, I am
still posting the apache log here for reference just in case.

The procedure I followed is to simply extract ms4w and update all paths to
include the drive letter "D:/" instead of the plain "/ms4w" in the
httpd.conf along with the un-commenting and setting alias for mapcache. I
have over 7 projects using it and I keep seeing "lck" files being generated
in the cache folder. There have been a few lock related logs as well. Not
sure if its related.

possibly stale lock after waiting on it for 120.01 seconds

The system's event viewer also has an error each time mapcache
crashes/Apache restarts itself.

Here is the OS and MS4W configuration:

Windows 2012 standard 64 bit OS
MS4W 3.1.4

It would be great if someone can please help me in this regard.

Thanks,
Varun
