You should not be monitoring /proc with the same Zabbix tools used to monitor a normal filesystem. When you stop monitoring the /proc filesystem like it is a regular filesystem, those alarms with go away.
Thanks for replying !

Zabbix, monitores all mounted partition, for that reason it is generating alarms like that. Because somehow those /proc partition are been mounted and looks like that myspell thing is trying to write on /proc;Or is alarming because is not possible to write there.

Since I find the issue I suspend this from the monitoring.

The other guys are planning to reinstall the OS, and in order to avoid this I was trying to find a way to remove those entries from /proc/self/mounts or a way to prevent this.

Thanks again !

I don't think the information above is correct and so you should look deeper into it.

In Zabbix you can configure which file systems to monitor in the zabbix_agentd.conf file.

If you search the net, you will find many examples of zabbix_agentd.conf to research.

Why do you want to change mtab or mounts? Don't! It would confuse the system.
Maybe your change attempts cause the strange bind mounts?
Anyway, update your zabbix! A bind mount (regardless if strange or normal) must not be monitored at all!

Which is not supposed to happen because there are other mounted partition which should have been show there.

Code:
[root@server ~]# mount -l
/dev/mapper/vg_umpom01brb-LogVol01 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/usr/share/myspell/shell/.myempty on /proc/25669 type none (rw,bind)
/dev/sda1 on /boot type ext4 (rw)
10.000.000.00:/umplogs on /var/UMP_LOGS type nfs (rw,nosuid,addr=10.000.000.00)
10.000.000.00:/DBBACKUP on /var/DBBACKUP type nfs (rw,nosuid,addr=10.000.000.00)
10.000.000.00:/opt/sysreports on /opt/sysreports type nfs (rw,nosuid,vers=4,addr=10.000.000.00,clientaddr=10.000.000.00)

Note that this might be caused by an automounter. Most of them mount only when the FS is accessed and therefore you don't see it in dfs output when it was not accessed for some time. I had that (rather strange) effect once on a Solaris system.

I hope this helps.
