Hi,
Same choke problems with some players and I also noticed instability
about fps servers after this update.
We run a Couter-strike 1.6 decicated linux Server, some Details:
[*] Amd Sempron 2500+ ;
[*] 512 ram ;
[*] OS: Debian Sarge ;
[*] Kernel : Linux 2.6.8-2-386
[*] Glibc : Release stable, Version 2.3.5
[*] 18 slot Slots ;
Also:
[*] Metamod 1.18p26 ;
[*] HLGuards 1.18 & SteamBan activated
Once patch applied, the server crashes randomly very often with the
following error :

So, I hope to see new update because of this crashes are really boring
:-( :-( .
Regarding these crashes. Can you see whats the last lines are in the
console?
The most common crashes occur when someone connects, when someone drops or
reconnect. But I have also got it randomly. The last strace came up with
this on the latest line at the console.

You're right.

It crashes randomly when a player connect / reconnect / drops. Also
randomly on change map.
I will try to run the server under gdb and try to reproduce the bug .And
i will post a
backtrace of the segfault error.
So... let's go. ^^
The crashes I get is actually kill() that are sent from the server. So no
coredump is made. (This strace was made by previous hlds-version)
strace:

notice 'kill(24956, 32)'. 32 is SIGTHR (thread interupt) and are sent to
pid 24956 which probably is a thread that hlds have started since the
parent pid was 24954.
I am also seeing a lot of these errors in the strace:
recv?(674183512, 0x4, 3217021340,
MSG_PEEK|MSG_CTRUNC|MSG_EOR|MSG_DONTWAIT|0xf00) = -1 E??? (errno -11)
-11 should be ( if I understand correctly ):
[EAGAIN] The socket is marked non-blocking, and the receive operation
would block, or a receive timeout had been set, and the timeout expired
before data were received.
But thats a legacy call. in errno.h it is specified:
#define EDEADLK 11 /* Resource deadlock avoided */
/* 11 was EAGAIN */
11 is now:
#define EAGAIN 35 /* Resource temporarily unavailable */
Which one that are used, I dont know. And if it differ due to the ABI that
are used.
I believe it is a threading and/or timing issue, since I notice that the
process gets <defunct> on crash at a massive use if 'ps aux | grep hlds'
In the ps manpage you can read:
"Processes marked <defunct> are dead processes (so-called "zombies") that
remain because their parent has not destroyed them properly. These
processes will be destroyed by init(8) if the parent process exits."
Ehm, did I make any sense? Gah, time for a drink with caffeine in it. I am
truly too tired for this...
