Email operations bring system to a halt

💬 General Discussion

Today I have begun experiencing problems with importing and deleting emails using the SuiteCRM web interface. Everything works perfectly for a few minutes, before the system grinds to a halt and becomes completely unresponsive. The only way to get things moving again is to restart Apache.

I have not installed any updates to the SuiteCRM or the Ubuntu server, nor have I made any customisations. A check of the Sugarcrm,log file reveals nothing of interest. The PHP error log on the other hand has some very strange things going on:

AdminUser@CRMServer:~$ sudo tail /var/log/apache2/error.log

Can anyone please tell me what is going on? My productivity has gone off a cliff today wrestling with this issue.

Thanks in advance,

After much digging around and testing, it seems as though the problem is actually related to a DNS error at my ISP.

Not sure how this results in the errors from the PHP log posted above, but once the ISP issue is resolved I may have time to revisit this.
