Hi All - might seem the same as other topics I’ve found in a search, but the circumstances of this one are slightly different and none of the solutions that appear in other topics are either applicable, or otherwise do not work.
I have an otherwise perfectly working Web application running on an Ionos server running CentOS. No problems in general, but then intermittently and without warning the server randomly starts to scream a Server 500 error for new requests.
Again (as reported in other posts), the fault seems to be (from examing the logs) in the cgi file reported as:
i. Unitialised variable $length on line 131 and 130 (appearing once for each line)
ii. Many repetitive reports of undefined symbol reference in line 118
In this case however, the problem is not with new loads, new apps etc. but with an otherwise working application that may go for days or weeks without any problems at all, followed by the random appearance of the error.
The solution is to simply run a killall [appname] and the connections start working again.
Anyone seen this one before / have any ideas of cause?
