[1.4] zbx_malloc: out of memory. requested '3084308801' bytes.

[zabbix_es]

It's related with web monitoring.

I have deleted all records of DB related with web monitoring and zabbix_server does not die, so this confirm that this issue is related with web monitoring.

Please, all, re-check that the patch was applied and server binaries were recompiled! We cannot reproduce this problem on our test server.

[alexandro]

My zabbix die with patch even when there are no web-scenaries at all and when present one http or https check with correct url

I can give access to server with this problem

[Alexei]

I would be interested in an access to your system very much. Please could you send connection details (SSH) to a l e x @ z a b b i x . c o m

[Alexei]

Thank you for providing access to your system! Finally we found what was wrong.

In /src/libs/zbxdbhigh/db.c, function DBdyn_escape_string, add:

int str_esc_len=0;

Please report if this helped.

[alexandro]

Yes, now zabbix doesn't die and web scenaries work.

[knarfS]

Thanks Alexei, this patch works for us.

[Eugene]

Thank's for all.

You can use last patch for 'out of memory'

[angch]

-Wall please

You really ought to add "-Wall" to CFLAGS, and pay attention to the warnings emitted. That way, this bug would have been caught much earlier.

Another example of a possible bug is in 1.4's src/libs/zbxdbhigh/hosts.c line 3235.

It currently reads

if( (graph_data == DBfetch(db_graphs)) )

when you probably meant it to be

if( (graph_data = DBfetch(db_graphs)) )

Line 1332's

applicationid = applicationid_new;

*might* be using an uninitialized applicationid_new variable as well.

[Alexei]

I see no problems here. By the way, -Wall does not show warnings about uninitialized variables, at least under gcc 4.1.3. Use -Wuninitialized instead!
