EEM script to monitor OSPF neighbor not working

Question

I'm trying to monitor a OSPF neighbor syslog notification event to trigger actions to remove a network statement.  I shut down the interface to the monitored neighbor and it removes the network statement which is good.  I am also trying to monitor the neighbor to come back up and then re add the removed network statement which is not working.  This may be a two part problem but I am receiving warnings that not enough vty lines are available.  I am not seeing that the network addition is working at all.  Here is my configuration.
event manager applet ospf-watch-down
event syslog pattern "OSPF-5-ADJCHG: Process 100, Nbr 1.1.1.2 on FastEthernet1/0 from FULL to DOWN"
action 1.0 cli command "enable"
action 2.0 cli command "config t"
action 3.0 cli command "router ospf 100"
action 4.0 cli command "no network 2.2.2.0 0.0.0.255 area 0"
action 5.0 cli command "end"
action 6.0 cli command "exit"
event manager applet ospf-watch-up
event syslog pattern "OSPF-5-ADJCHG: Process 100, Nbr 1.1.1.1 on FastEthernet1/0 from LOADING to FULL"
action 1.0 cli command "enable"
action 2.0 cli command "config t"
action 3.0 cli command "router ospf 100"
action 4.0 cli command "network 2.2.2.0 0.0.0.255 area 0"
action 5.0 cli command "end"
action 6.0 cli command "exit"
Here is the EM syslog error message " %HA_EM-3-FMPD_ERROR: Error executing applet ospf-watch-down statement 3.0"  I am having the EM end and exit so I'm not sure why it's running out of CLI sessions.  I'm also getting this one too " %HA_EM-3-FMPD_CLI_CONNECT: Unable to establish CLI session: no tty lines available, minimum of 2 required by EEM"
I've tested the ospf-watch-up and ospf-watch-down on its own after clearing all of the sessions and they each work on their own.  I think this is a bug where eem won't release the session.

I know this is a old post. I was able to use the solution below, but I am having one problem.
Using the below config I am able to receive a email anytime my voice port is in any other state than ON HOOK. The problem I have is the script runs every 30 seconds and I receive an email every 30 seconds the line is in any other state than "ON-HOOK". 
Is there a way to have only one email generated ONLY when the state changes from the previous state? 
example : the line is on-hook, changes to off-hook or park or whatever- a email would be generated.  ( only One email). not one every 30 seconds...
               The line goes from Off-Hook back to IDLE.  - A email would be generated to advise the line has been restored to a IDLE state. 
scheduler allocate 20000 1000
event manager environment _email_from [email protected]
event manager environment _email_to email [email protected]
event manager environment _email_server smtp-server.isp.net
event manager applet check_1/0/0_if_NOT_ONHOOK
 event timer watchdog time 30
 action 001 cli command "enable"
 action 002 cli command "show voice port summ | include 1/0/0"
 action 003 foreach line "$_cli_result" "\n"
 action 004  regexp "on-hook" "$line"
 action 005  if $_regexp_result eq "1"
 action 006   exit 0
 action 007  end
 action 008 end
 action 009 syslog msg "PORT_1_is_in_any_other_state_then_on-HooK!"
 action 1.0 mail server "$_email_server" to "$_email_to" from "$_email_from" subject "$_event_pub_time:Test EEM port 1/0/0 is SHORTED ie IN ALARM" body "TEST Body"
end
Any ideas?
