Server error compiling C# code #185

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Just try to upload any C# code

I'm getting following error emailed me during compilation of my code:

** ERROR **: shm_semaphores_init: semget error: No space left on device. Try 
deleting some semaphores with ipcs and ipcrm
or increase the maximum number of semaphore in the system.
aborting...

** (process:2021): WARNING (recursed) **: Thread (nil) may have been 
prematurely finalized
Stacktrace:

** (process:2021): WARNING (recursed) **: Thread (nil) may have been

/lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe0) [0xb7d0a450]

As i understand it - it's mono runtime error, and it says time to free some 
memory on server.
Like this:

ipcs |grep nobody | awk '{print $2}' | xargs ipcrm sem

And dont forget to set:

kernel.msgmni = 1024,
kernel.sem = 250 256000 32 1024

or even bigger.

P.S.: it's a good moment to upgrade mono on server... Current version is ugly 
(keeping in mind C# state of art as a language and mono as a runtime env.).

Mine conf: Windows 7 Ult, latest Chrome

I am getting the same error and can you please treat this with "Priority - 
High" and resolve

Another vote on priority: High.
I worked on a C# code for several days and now i can't post the results to 
compete.
Steps to reproduce:
Just post any C# code you like.

Hi.

This may be related to a known Memory Leak of Mono C# compiler.

https://bugzilla.novell.com/show_bug.cgi?id=588689
(Memory leak while running Mono on a scheduler timer)

Acording to the Bugzilla report, It was fixed on a recent Mono build, with 
hotfix available for previous 2.4.x versions.

Regards

BTW, another vote for 'High' priority. Unless extremely lucky, no C# code can 
be submitted while this isn´t fixed.

Had 7 failures before finally getting through almost 24 hours by pure luck 
trying it again.  Really pretty ridiculous when a 5 minute hotfix would fix it.

Why this isn't a high priority I have no idea - a 5 minute hotfix would fix an 
issue that is literally causing an entire language to not be usable in a coding 
contest.

Original comment by themend...@gmail.com on 1 Oct 2010 at 12:29

GoogleCodeExporter commented 9 years ago
I keep failing for the same reason. This should be a high priority as people 
using C# can't get anything to compile.

there is no C# in the top of the ranking list
people might come to think C# is no good =)
look liek a sort of provocation =)

when it's going to be fixed up?
my bot is ready to go =)

This needs admin attention, hopefully Jeff can do something about it.

Original comment by jokeserver on 8 Oct 2010 at 4:36

Probably the only real fix is to upgrade C#, Issue 101 has a post with an easy 
method for doing so.

One additional thing to remember now though is to update the cloud server build 
script at the same time the main server is upgraded so everything will still be 
running the same version.

This issue effectively kicked us out of the game, and we were in top30.
Admin, are you alive, or should I say, DO YOU EXIST?

Seems that it's fixed. I have successfully submitted 3 times in a row without 
any issues. Remember that your C# code must be compliant with .NET framework 
v2.0

Seems that it isn't. I'd tried with my previously working code.

I cant believe they still didnt fix the error, 
no c# till 120 position cause the error, 
they are scared about sharp coders and want us all out of the competition!

Still having the same issue.
Code compiles just fine with mono 1.2.6 locally.

getting the dreaded:
** ERROR **: shm_semaphores_init: semget error: No space left on device. Try 
deleting some semaphores with ipcs and ipcrm
or increase the maximum number of semaphore in the system.
aborting...

again and again.
