 Hi guys,

 We are using the Varnish version 3.0.5 and we have increased the size of
 the files that are cached from 10MB to 100MB. After this change once a day
 Varnish crashes with the following error message:

 I have disabled transparent hugepages as mentioned here - https://www
 .varnish-cache.org/docs/3.0/tutorial/platformnotes.html however this
 didn't fixed the issue.
 I'm monitoring all varnish stats so if you need any other information
 please let me know.

 Looking forward to hearing from you.

 Regards,
 Andrei
