Hi I have several ICX6430/ICX64S08030c that once in a while have a very slow or no response at all to my telnet sessions. I can exclued IP routing issues and probably spanning-tree issues as well, since I have connectivity to other switches that are behind the one that shows the problems. Normally only a reboot of the switch helps.
Does anyone have had the same experiences? Is there any less invasive method to get the device back to a fully manageable situation?
Any hint is appreciated.

Never had that issue, but I would highly recommend upgrading the firmware to to 8030j
To upgrade it:
copy tftp flash 10.1.144.4 ICX64S08030j.bin primary
If the boot code is lower than Boot Version 10.1.05T310, you should upgrade it too:
copy tftp flash 10.1.144.4 kxz10105.bin bootrom
If this is a PoE model usually has a "P" in it like ICX6430-48P then you may as well check the firmware of it via
show inline power detail | begin Firmware
and if below 2.1.0 Build 004 then upgrade it:
inline power install-firmware stack-unit 1 tftp 10.1.2.3 icx64xx_poeplus_02.1.0.b004.fw
Anyway, beyond this for us to help you are going to need to post your configureation.
That said, I highly recommend you use SSH instead; it is MUCH more secure.
Basically go int Global Configureation mode and make sure to setup a username:
username someone password somepassword
crpyto key generate rsa mod 2048
Probably should make an ACL to control access, too:
access-list 99 permit host 10.1.2.3
access-list 99 permit 10.99.0.0 0.0.255.255
access-list 99 denay any log
ssh access-group 99
May as well set some parameters:
ip ssh authentication-retries 2
ip ssh timeout 30
ip ssh idle-time 30
ip ssh scp disable
Anyway, please post your config and let us know.
