How to tell if Zabbix has memory leak?

[Palmertree]

Maybe there should be a NET-SNMP version check like there is for php when running throught the config install. Just a thought.

I have found why my SNMP pollers were leaking memory. I wanted to share this with everyone because this might be a problem for a lot of people and it took me a few days to figure this out. The problem is not in the Zabbix code but the NET-SNMP libraries. There is a major memory leak in the libraries for "NET-SNMP Version 5.4". I was able to determine this by running "Valgrind" and saw the "varbinds" leaking like crazy. NET_SNMP version 5.4 is used in most yum installs. Net-SNMP Version 5.4.1 fixes these memory leaks. I had to down load the newest version and compile it. After installing version 5.4.1 of NET-SNMP you must recompile Zabbix Pre 1.4.3 (do not use 1.4.2, has a memory leak in the trappers).

NET-SNMP Release Notes
Release Name: 5.4.1
Notes:
*5.4.1*

snmplib:
- [BUG 1619827]: link libraries against needed external libraries
- [PATCH 1616912]: fix memory leak in UDP transport code
- [PATCH 1592706]: fix memory leak when cloning varbinds

Do you think this applied to x64 too?

It seems yum installs even a lower version:
Installed Packages
net-snmp.x86_64 1:5.3.1-24.el5_2.2 installed

net-snmp stil leaking ...

Sorry to fire again an old issue but ...

I have just set up a fresh Zabbix-1.6.2 installation that works very fine as long as the net-snmp support is not embedded with it.
I have firstly compiled net-snmp-5.4.2.1 on my Redhat Enterprise Linux 5.3 . All the compilation went fine. Then, I have configured Zabbix-1.6.2 with the --with-net-snmp configure switch, compiled it, ran it and ... the server eat my memory like hell.
More than 3GB eated in less than 5 hours with 45 snmp-enabled pollers. I stopped it before it consumes the 16GB of swap ...

I have verified that the leakage was really in the net-snmp distribution by compiling Zabbix without it support and yes, the leakage went gone.

Anyone knows a distribution of net-snmp that fits correctly with Zabbix without consuming the memory? or maybe, the correct switches to configure/compile net-snmp-5.4.2.1 to avoid the memory consumption ?

Thanks in advance ;-)
