Well after some reviewing by the crack set of server admins here, ktrain and Negley, we have found that some issues we are seeing are linked directly to Metamod and AMX.
We highly suggest that all Server Admins do the following:

Use Metamod 1.17p21 & Jussi's amx modx 1.01

I also have found from searching around that Metamod-P 1.17.4p23 may also be a good solution to helping correct issues.

Metamod-P is enhanced version of Metamod. It has dynamic link-entities and automatic detection of Mod DLL and other improvement to allow it work with future Half-Life Engine updates and new Mods and updates.
--------------------------------------------------------------------------------
What is special in this version of metamod?

• Hardcoded linkents have been replaced with dynamic linkents. No large list of entities that get outdated fast as new mods come and old ones update.


• Extra enginecallback function slots, for future engine updates. Valve have to add 128 new functions before Metamod-P gets out of date.


• Autodetects gamedll for unknown/new mods (so you don't have to use metamod-config to make Metamod-P work on those mods).


• Because of reasons above, you basicly never need to update metamod again anymore. This works all future mods and updates.


• Better performance/less CPU usage than original Metamod

If you are a server admin and use any of these, please let us know how your server is functioning over in the Server Admin section.

BicB@ll has also noted in the Server Admin section that the map cycle may need to be edited as a small issue with optimizing textures has cause some fun, but obvious errors between HI_Basque and HI_efreeti.
You can read about it here. It is suggested that you make sure the maps aren't next to each other on the map cycle and avoid switching between the two maps.

I have a few more thank-you to had out here.

First is the the guys over at http://www.trunetworks.com
They have given us such great support during the past 2 releases with file mirrors. They alone this release have provided a huge chuck of mirrors for HI1.4.
Many thanks to you guys for the support.

I also have to give MJCS and the staff over at http://www.HLGaming.com a huge hug. These guys not only provide us with our webspace, but they are also our FTP providers and major players when it comes to file hosting. I thank-you guys for believing in us and all the support you give!!!!
