NethServer Version: NethServer release 7.4.1708 (Final)
Module: phpLdapAdmin

Hi all, i have this error when I load phpLdapAdmin (@stephdl module) page:

Warning: require(): Unable to allocate memory for pool. in /usr/share/phpldapadmin/htdocs/index.php on line 52

Warning: require_once(): Unable to allocate memory for pool. in /usr/share/phpldapadmin/lib/functions.php on line 248

Notice: Undefined variable: _SESSION in /usr/share/phpldapadmin/lib/page.php on line 379

Fatal error: Call to a member function getValue() on a non-object in /usr/share/phpldapadmin/lib/page.php on line 379

Can you help me?

Thanks in advance,
Pasquale

Do you use php-scl ?

[pasing]

@stephdl I don’t use it.

Any caching system (APC, opcache…) in use?

[stephdl]

Can you check in the /etc/phpldapadmin/phpldapadmin.conf if you don’t have a binary password for the ldap bind user

Now that you asked me, I had a doubt and I checked.
Some time ago, I installed php-apc to test it with wordpress, but then I never used it and uninstalled it.

This happened before installing phpLdapAdmin.
So far, I don’t remember having never found this problem.
Do you think this is the cause?

According to some web search the error is related to php (or cache) memory.
You can try to increase the php memory limit. If using the stock php version:

config getprop php MemoryLimit
config setprop php MemoryLimit 512
signal-event nethserver-php-update

I have checked in the /etc/phpldapadmin/ folder and i found only config.php file.
In the file bind_pass is set.

Not in front of a computer, sorry

I tried to increase the PHP Memory limit but it didn’t work, so I looked into the web how to increase APC (cache) memory.

I share it in case it may be useful to someone else.

Edit the file /etc/php.d/apc.ini and set

apc.enabled = 1
apc.shm_segments = 1
apc.shm_size = 256M
apc.ttl = 7200
apc.user_ttl = 7200
apc.gc_ttl = 0
apc.mmap_file_mask = "/tmp/apc.XXXXXX"

Restart web server Apache.

For display exact APC memory usage i have copied /usr/share/pear/apc.php to /usr/share/phpldapadmin/htdocs/apc.php and load http://your-server-here/phpldapadmin/apc.php.

source for apc settings and display APC cache information:

[stephdl]

could you edit your topic and add the mention of apc cache, please

I’m sorry, I integrated by inserting the source.
