Resource LImit is reached

[tenbergen]

I have got the following error message several times over the last few days:
"Resource Limit Is Reached
The website is temporarily unable to service your request as it exceeded resource limit. Please try again later. "

When I look at the Apache log I get many, many lines similar to
[Fri Oct 23 00:23:29.755499 2015] [:error] [pid 988568:tid 139781059012352] mod_hostinglimits:Error on LVE enter: LVE(566) HANDLER(x-httpd-php54) HOSTNAME(squirrelslair.ca) URL(/tinytinyrss/backend.php) TID(988632) errno (7) Read more: http://e.cloudlinux.com/MHL-E2BIG

Any idea what might be causing this? Thanks!
