VPN overview not working properly

[geocast]

Good Morning

Since a few day I been having trouble with the IPSEC overview diag_ipsec.php
When I try to open it, it either takes ages to load (Can take up to 5 Min) or it doesn't load at all.
Towards that I had the issue, that all VPNs would crash (currently 38 in total) after a few minutes.

First it was the issue that the kern.ipc.nmbclusters was to small. I raised it to 1.000.000 and since then I had no more issues with this.
The VPN crashes seem to have ceaset since I reinstalled pfsense over itself.
But the trouble with the overview is still a problem

The only thing I can find are these logs

Oct 13 08:51:39 fw php-fpm[31282]: /diag_ipsec.php: XML error: Mismatched tag at line 2 in /tmp/smp_status.xml
Oct 13 10:01:33 fw php-fpm[19611]: /diag_ipsec.php: Error during reading of status from IPsec

and a crash report

PHP Errors:
[13-Oct-2015 09:07:05 Europe/Zurich] PHP Fatal error:  Maximum execution time of 900 seconds exceeded in /etc/inc/xmlparse.inc on line 84

Filename: /var/crash/minfree

I'm running PFSence on an Alix APU 1D4 with PFsense 2.2.4
Addons I only have pfblockerng, which I uninstalled to test, but no results.

Any advice what to do next?

Thanks!

EDIT:

Just saw that I can't even stop the IPSEC service. When I press Stop, it says it's been stoped and carries on and the VPNs won't start either

Logs from IPSEC are justed flooded with

charon: 03[KNL] creating rekey job for CHILD_SA ESP/0x24a4dad5/83xxxx
Oct 13 10:33:12 charon: 03[KNL] creating rekey job for CHILD_SA ESP/0x5c1c4cc5/8xxxx

Seems to be linked to this problem

https://forum.pfsense.org/index.php?topic=99604.0

I've updated to the latest 2.2.5 Version today.

Report back how I goes

UPDATE:

Seems to have done the charm.
Issue that I have left, is that the SAD tab is flooded with entries. Most of them coming from the same IP.

Is there a way to manualy clear all of them?
