Cannot allocate memory

xavierk

I just upgraded to Ice 3.4.1 and using Mumpi v2.2.1 for Mumble 1.2.3 on Linux Centos 5 x86_64

Getting the following error message

Fatal error: Uncaught exception ::Ice::UnknownException { unknown = Thread.cpp:521: IceUtil::ThreadSyscallException: syscall exception: Cannot allocate memory } thrown in /home/xxxx/public_html/mumble/classes/ServerInterface.php on line 64

I tried changing the memory_limit in my php.ini from 48M to 64M and now to 256M with no effect.

The related lines are

$initData = new Ice_InitializationData;
                                $initData->properties = Ice_createProperties();
                                $initData->properties->setProperty('Ice.ImplicitContext', 'Shared');
                                $ICE = Ice_initialize($initData);

Ideas/Suggestions? I'll ask Kissaki to post any other related information.


Thank you,

Hi,

The error indicates that the initialization of the Ice communicator couldn't create a thread because of resource limits being reached. Does the error occur soon after startup? The best to investigate this would be to try to create a small Ice PHP test case that reproduces the problem.

Cheers
Benoit.

Created a test file with the following:

<?php
  require_once 'Ice.php';
                                $ICE = Ice_initialize();
?>

and getting the following:

Fatal error: Uncaught exception ::Ice::UnknownException { unknown = Thread.cpp:521: IceUtil::ThreadSyscallException: syscall exception: Cannot allocate memory } thrown in /home/xxxx/public_html/mumble/admin/test.php on line 3

Ideas? Thank you

Alright, so the problem seems to be specific to ice.php or ice in general. Since most of the ice tools were installed from the yum.repos, excluding ice.cpp and ice.php, which I compiled. I decided to completely remove them and rebuild them.

Perhaps I rushed last time, this time I was more cafeful to test everything and this is what I got after building ice.cpp while running 'make test'.

testing udp... ok
testing udp multicast... UdpTransceiver.cpp:170: Ice::SocketException:

The sending of a UDP packet on a multicast address failed because of permission issues. Which CentOS version do you use? Is the firewall enabled on your machine? In any case, I wouldn't worry about this failure if you don't use UDP multicast.

Cheers,
Benoit.

No, I don't use the UDP multicast. It is a Centos 5.5 x86_64 with firewalling and both inbound/outbound ports blocked.

xavierk

Well the issue is resolved. Tweaked some php settings, completely removed ice and reinstalled/recompiled and now it seems to be working.
