I recently upgraded to 4.0. While the upgrade went smooth, I started noticing many issues afterwards:
Memory issues - NIC Server crashing frequently
Custom UDS issues - Netscaler parser that was working beautifully now gives me an access violation error. I recreated the device and it was discovered as "Unknown"
Views errors - I have a multi-site environment and had specific group filters for each site. Now enVision tells me that the views have no devices even though the group filters show the devices there. I have recreated the group filters to no avail.
Support has been able to validate these issues (after many many tries) but have not offered a solution yet.
Is anyody else seeing similar issues? Did find any workarounds?
