SMTP_CLIENT Array index out of range

[david]

When using SMTP_CLIENT (network lib 121) on an ILC 170 the PLC went to stop giving an Array index out of range error.
I was able to make a screenshot, but there was not much time to debug.
Any idea what could be the problem? I was not able to reproduce the problem.

hi,

1. do you have the error always, or only randomly ?
2. is the index error in SMTP_CLIENT or IP_CONTROL ?
3. can you make a small example project where the error occurs

[david]

The error only happened once
It is in IP_CONTROL
As it only happened once, it is difficult to simulate, if you want, I can sent you the complete project.
