Upgrading 13.0 Build 61.48 to 13.0 Build 64.35

anyone having issues upgrading NetScaler 13.0 VPX Build 61.48 to 64.35?

Tried this several times now, even with a brand new import of 61.48 and a re-download of 64.35, and each time it's hanging on "Extracting golang..."

After a while it will time out with a "missed heartbeat" error and reboot, but i don't trust the state that it's been left in, as it doesn't appear to have finished the upgrade...


Anyone else seeing this?

Hi Carl,


I've been doing upgrades via the console/putty for the last 5+ years ever since a GUI upgrade failed on me and caused no end of issues :-(

The issue occurs every time upgrading from 61.48 to 64.35, but i've never tried upgrading from an earlier 13.0 version, which I'll try in the next day or two...


I'm assuming from your question you've not experienced this... 


Attached is a screen grab of the upgrade as it's failing.... after 15 minutes of sitting on Extracting golang, the upgrade crashes out with a core dump of the nsnetsvc process


One thing I forgot to mention, the NetScaler is being monitored by an ADM but I'm not using that for the upgrade...
