Recently, I've found out that rcon does not work if the server is up for about a month. I did some investigation and discovered this most probably happens due to memory consumption of silEnT server. I tested a bit, run test server with Omni-bot (so there's someone who play) and the rest you can see below.
Is it possible it's a mod issue or should it be reported to OB dev team?

You can get more detailed information of what is using the memory with following commands:
pmap -x <process id>
and
cat /proc/<process id>/smaps
Take a snapshot and after some time when the memory consumption has risen significantly, another snapshot.
Also, there are engine related reasons why you should restart the server more often then one month interval. The server time will rotate for example.

Memory leaks come from OB. I also get those. More bots you run more memory leak you get. I had reported that to crapshoot but seems like he is busy ...cos he used to reply pretty fast before.

I don't remember any memory leak information being reported to me. Please send it. One thing that you can do is set SleepBots to 1 in the omni_bot.cfg which will disable bots while there are no humans on the server; reducing cpu cycles and memory usage during those times. Once a human joins, the bots will resume from where they were.

Possible small leak in qagame.so?
This is not relevant, we shoud get more samples, for instance from 1h intervals. If the memory would grow constantly we could consider the memory leak.

I don't see significant differences in these regarding qagame given that memory usage differences can be caused by other factors as well. One small leak we have found though, which happens when reading files with Lua scripts.

anon is probably a stack memory, so I guess we may not care about it so much. We would need more samples, as I said, to be certain about the results.

Well, anon blocks can be both, actually. For example thread stacks can be anon blocks. But let's not argue about it, as we cannot formulate any conclusions based on 2 samples only, in my opinion.

That is true and it is stated already for qagame. However, the 140 MB increase in the etded.x86 is significant enough to see there is an issue. Accompanied by the fact that it is already known before hand that there is a memory leak problem. These snapshots are, in my opinion, clear enough to point to the direction where the memory concerned in the topic is not being freed. That is why I posted about two snapshots instead of doing a cronjob task for it. The 6 MB with qagame can come from a number of naturally occurring differences and it is not enough to formulate conclusions.

In fact, the misunderstanding comes from my busy head and the fact that I didn't notice the difference in etded.x86 as I was writing the post from work and didn't focus too much on your post. Sorry for that. The rest remains true of course
