First I have attached is a simple patch to eliminate the following php
warning that I am seeing in my apache error log file:
[error] PHP Warning: Call-time pass-by-reference has been deprecated -
argument passed by value; If you would like to pass it by reference,
modify the declaration of fsockopen(). If you would like to enable
call-time pass-by-reference, you can set allow_call_time_pass_reference
to true in your INI file. However, future versions may not support this
any longer. in /home/www/ganglia.php on line 273
I am still using apache 1.3.28 with php 4.3.3.
Second, occasionally my web browser is getting connection errors with
broken images that stop the page refreshing when it loads the ganglia
page and at the same time it happens I get these in my error log:
[notice] child pid 571 exit signal Segmentation fault (11)
I assume these are coming from the rrdtool process that the php script
is executing to generate the graphs. Any idea why rrdtool would be seg
faulting or how I could debug it. This doesn't happen too frequently,
maybe a few times a day, but they seem to happen in spurts. Could this
occur when rrdtool is trying to read a file at the same time gmetad is
writing to it?
Finally, my apache server appears to be leaking memory. Could the
ganglia php scripts be causing a memory leak? We have several other
webservers all with the same version of apache and only the ganglia
webfrontend has this leak. My temporary fix is to just restart apache
every night, since even the weekly logrotate & restart was too long to
wait.
