Comment by Aleksandrs Saveljevs [ 2014 Jan 31 ]

Since program counter is not available for this architecture (i.e., no information is provided about the instruction on which the server crashed), the disassembly is not particularly useful.

Is the crash reliably reproducible? Would it be possible to start the server with DebugLevel=4?

Comment by Oleksii Zagorskyi [ 2014 Jan 31 ]

And as many of crashes fixed already after 2.2.1 - would be good to retry with latest pre-2.2.2rc1

Comment by Sergey Berdnikov [ 2014 Feb 03 ]

Yer, bug is reliably reproducible. I can't start zabbix server on this host)
Log with DebugLevel=4:

Version Zabbix 2.0.10 works fine with no problems.

Comment by Pablo Ruiz [ 2014 May 01 ]

Patch fixing this issue.

Comment by Pablo Ruiz [ 2014 May 01 ]

Hi,

I've just hit this issue while upgrading a zabbix server from 1.8 to 2.2, and after a couple of debugging sessions, I've found the problem to be caused by an unaligned memory access at src/libs/zbxdbcache/dbconfig.c:921:

Program received signal SIGSEGV, Segmentation fault.
0x0000000100089070 in DCsync_items (result=0x1002d83e0) at dbconfig.c:921
921 item->hostid = hostid;

(gdb) list
916 update_index = 1;
917 }
918
919 /* store new information in item structure */
920
921 item->hostid = hostid;
922 item->type = (unsigned char)atoi(row[3]);
923 item->data_type = (unsigned char)atoi(row[4]);
924 DCstrpool_replace(found, &item->key, row[6]);
925 DCstrpool_replace(found, &item->port, row[9]);

At this point 'item' pointer points to an ZBX_DC_ITEM, which was obtained from a hashset hold by global 'config' struct. And after inspecting "include/zbxalgo.h" for hashset's structs declarations, I found ZBX_HASHSET_ENTRY_T typedef/struct, which has it's data member aligned on a 4 bytes boundary, but this (obviouslly) fails on 64bit SPARC, as this platform requires strict aligned memory access.

(gdb) p item
$44 = (ZBX_DC_ITEM *) 0xffffffff5804c3d4

(gdb) p 0xffffffff5804c3d4 % sizeof(uint64_t)
$45 = 4

Si, as a fix I've simple added some padding based on the current pointer length:

ZBX_HASHSET_ENTRY_T
{
  ZBX_HASHSET_ENTRY_T     *next;
  zbx_hash_t              hash;
  /*
   * We need to pad here to avoid unaligned access
   * to data on struct aling archs like SPARC.
   * 2014/05/01 -- pablo.ruiz _at_ gmail.com
   */
  char                    padding[sizeof(void*) - sizeof(zbx_hash_t)];
  char                    data[1];
};

I am attaching a patch fixing this issue.

Regards
Pablo

Fix available in svn://svn.zabbix.com/branches/dev/ZBX-7729

Comment by Andris Zeila [ 2014 May 09 ]

I changed procfs.h include to mirror the changes made in ZBX-5243, please review r45227.

Comment by Andris Zeila [ 2014 May 09 ]

Added check to avoid declaring zero length padding array (which is universally supported).
Please review r45266

Moved AC_CHECK_SIZEOF macro after OS check because CGLAGS might be updated during OS check (Solaris) r45273

Comment by Andris Zeila [ 2014 May 09 ]

Successfully tested, please review the changes

Comment by Alexander Vladishev [ 2014 May 10 ]

The fix should be ported in 2.0 and 2.2.

nikolajs.agafonovs Proposed fix need to be applied to 2.2 and up.
2.0 do not contain this bug.

Fix for 2.2 is available in svn://svn.zabbix.com/branches/dev/ZBX-7729_22

Fixed in pre-2.3.0 (trunk) r45288
