 Description   

zabbix_sender utility makes duplicates and send them to Zabbix server. For example:

  1. ./test.pl 200 > test2 && ./zabbix_sender -z 192.168.137.22 -p 10051 -T -i ./test2
    info from server: "Processed 250 Failed 0 Total 250 Seconds spent 0.003012"
    info from server: "Processed 250 Failed 0 Total 250 Seconds spent 0.003321"
    info from server: "Processed 100 Failed 0 Total 100 Seconds spent 0.001202"
    sent: 600; skipped: 0; total: 600
  2. cat ./test2 | wc -l
    400

We have only 400 records in file, but zabbix_sender sent 600.

It happens only with zabbix_sender installed on Solaris 10/11.

Problem reproduced. The bug is observed if a number of records in the input file is more than 250 (maximum for one connection, defined in src/zabbix_sender/zabbix_sender.c) and the input file is read either directly or via redirected input:

$ cat 400_records | zabbix_sender .... -i -     <--- ok.
$ zabbix_sender .... -i 400_records    <--- bug occurs.
$ zabbix_sender .... -i - < 400_records    <--- bug occurs.

Attachment "zabbix_sender.c.ZBX-5732_Solaris.patch" contains a quick-fix for Solaris.
To apply the patch:
Change to Zabbix source directory, for example:
$ cd zabbix-2.0.4rc1

Apply the patch, for example:
$ patch -bNp1 -i /tmp/zabbix_sender.c.ZBX-5732_Solaris.patch
patching file src/zabbix_sender/zabbix_sender.c

Check the difference between the original and patched files:
$ diff src/zabbix_sender/zabbix_sender.c.orig src/zabbix_sender/zabbix_sender.c
107c107
< exit(FAIL);
—
> _exit(FAIL);
195c195
< zbx_thread_exit(ret);
—
> _exit(ret);

It is a quick-fix for Solaris, but has not been tested on other platforms.
