Hello people: I have changed the configuration of the RRA files for my pnp graphs and now I seem to have some memory issues this is the error I see in the pnp4nagios graphs: "Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 40 bytes) in /usr/local/nagios/share/pnp/include/function.inc.php on line 1411" My rra.cfg configuration file looks like this: # # PNP RRA config # # The estimated size of the files will be # # 2880 entries with 1 minute step = 48 houres # RRA:AVERAGE:0.5:1:2880 # # 210240 entries with 5 minute step = 2 years # RRA:AVERAGE:0.5:5:210240 RRA:MAX:0.5:1:2880 RRA:MIN:0.5:5:210240 RRA:MAX:0.5:1:2880 RRA:MIN:0.5:5:210240 As you can see we need 5 minute precission for 2 years in our graphs, this results into 5M rrd files for one measuring point. I have tried changing the "memory_limit " in my php.ini file from 8M up to 256M and restarted apache every time but the problem persists. Is there a hardcoded memory limit in the /usr/local/nagios/share/pnp/include/function.inc.php file? has anybody seen this problem before? Any help hint, recommendatoin or comment is deeply appreciated Regards Marco
