gkrellm has a memory leak

[bulltza]

Binary package hint: gkrellm

I am using gkrellm 2.3.1-1ubuntu2 in Ubuntu Hardy 8.04

I have had ubuntu running for a month and I had to reboot the computer every 7 days because I was getting out of memory RAM after 7 days. I had been monitoring with ps aux and the only software using more and more memory ram every day is gkrellm. I am attaching 1 files with the graph of my memory ram (calculated with the command $(free|grep Mem:|awk '{print ($3-$6-$7)/$2*100;}')): As you can see in the graph I rebooted the system the 29th of january and the 30th I swiched on some programs and I left the computer running non stop. The 3th of february I arrived home again and you can see how there is a trend of usage of the memory ram. Then I did a couple of things (switch on torrents and watch a movie etc) and that is why there is a spike that day but you can ignore that part, only the trend is important.

2- ps aux after I left the house
<code>
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
franky 6265 6.5 2.2 28544 11552 ? S 23:47 0:01 gkrellm
</code>

3- ps aux when I arrived home 5 days later
<code>
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
franky 6265 3.8 7.9 58508 40532 ? S Jan29 259:13 gkrellm
</code>

Only gkrellm seems to be growing up (nautilus also did but only 0.1% the rest was all the same) and I just killed it and look for anything in internet and report it here, after killing it it seems I recovered my lost 8% RAM

It is not a very important memory leak, about almost 10% of my 512mb of ram over 5 days, but it is annoying in my server and I have been using gkrellm since I was born in linux some years ago. Taking it out from my server is a big pity.

I had similar graphs of my server in 7.10 and in 6 months I had no memory leaks and I was using gkrellm aswell.

I have probably found the reason of the memory leak in google, have a look here http://www.nabble.com/-patch--memory-leak-td16410788.html

I dont have any themes or plugins customised that were not in the repository of Hardy, here is what I have installed: (from aptitude)

It is my first bug report, I hope everything is clear, please update the gkrellm package with the patch I posted and lets see if that solves the problem.

I have the same problem. Same version of gkrellm, same version of Ubuntu. I left my web server running for a few weeks, I come back to check on it, and to my horror it is so sluggish that it takes minutes just to log in. gkrellm was the culprit, taking up nearly 400 mb of ram!
