radios die

    I have a setup in which I've constructed 2-soekris 4826's and one soekris 4521 in one enclosure. The 4826's are each loaded with 2-100mW prism minipci cards and collectively they power a 17dBi Quad 90 degree Sector antenna array. The operating system used for all of these boards is pebblelinux v. 2.4.26. The 4521 holds the backhaul radios, is linked to the 4826's via eth0 and eth1, and runs flawlessly. However the 4826's exhibit a serious problem in that when a number of clients associate to the AP the/a radio will just go deaf and mute.Currently less than 10 clients are assigned to any AP/radio. Observations seem to indicate the more clients that associate to the AP the more likely it will shut down.Thankfully adding iwpriv <interface> reset 1 as a cron job every three minutes keeps it going for the time being but I have other systems running that are being taxed much more than these with no problems whatsoever. I must emphasize that its just the radio's that are
 acting up, the eth ports continue working fine, the soekris keeps chugging along. Its just the radio's.This leads me to believe there is no problem with power supply as this, as seen in past, will reset the entire soekris board and this isn't happening.The same os is running in other systems with the same version of hostap with no problems whatsoever.This is the vendor radio info:

There is not alot of info to be gleaned from the logs to indicate a problem, so at this point I'm pretty much in the dark as to why this is happening. Any help with this would be very welcome. Thank you!

Ahhh...imagining that irresistible "new car" smell?
