[Observium] Allowed memory size of 268435456 bytes exhausted during the pooling for one host

Hi

one host cannot finish the pooling procedure, even though i run it separateley:

./poller.php  -h router_host_name  -d

.....

.....

including: includes/polling/cipsec-tunnels.inc.php

after that a lot of messages of this kind: .....

cipSecTunStatus.3157 = active

cipSecTunStatus.3158 = active

cipSecTunStatus.3159 = active

cipSecTunStatus.3160 = active

.....

Then the pooling terminates with:

SNMP_STATUS[TRUE]

PHP Fatal error:  Allowed memory size of 268435456 bytes exhausted (tried to allocate 256 bytes) in /opt/observium/includes/snmp.inc.php on line 654

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 256 bytes) in /opt/observium/includes/snmp.inc.php on line 654

I increased the memory limit to 256 MB in the php.ini, however still does not work.

It happens only with one host out of about 200 hosts. I have about 7000 ports in Observium.

Platform is:

CentOS release 6.6

php-5.3.3-40.el6_6.x86_64

httpd-2.2.15-39.el6.centos.x86_64

Observium CE 0.14.11.6000

Do you have any ideas ?

many thanks
