Cisco Switch TCL SMTP timeout

Question

Hello I have some problem with cisco switch if i use SMTP event over TCL.
My TCl scrip contain code:
if [catch {smtp_send_email $mail_msg} result] {
error $result $errorInfo
#code for dump to file
} else {#code if all ok}
If internet is work script work fine. but if internet is down switch try send message long time and script "Process Forced Exit"
I have error
Jul 12 23:35:10: %HA_EM-6-LOG: event.tcl: Process Forced Exit- MAXRUN timer expired.
Jul 12 23:35:10: %HA_EM-6-LOG: event.tcl:     while executing

I try change Maxrun timer but it not help (i have same error but it not print before time not end).
I try ios for switch 150-2.SE4 | 122-55.SE8 | 122-44.6
I try this code on cisco router, it work fine(if smtp server not avalable script print error 1-2sec).
Thank you.

If the mailer server is not listening on tcp/25 or otherwise refuses the connection, then the socket attempt should die quickly.  If the mail server is truly unreachable, then the socket will never timeout until the EEM policy terminates.  This holds true on the latest version of EEM on routers as well.
