The pollinterval parameter has no influence on the communication  
between server and client, so this shouldn't be a problem. But rather  
than increasing that, I would first increase the pollfreq (setting  
this lower than pollinterval is pointless anyway). So in ups.conf

     driver = usbhid-ups
     port = auto
     pollinterval = 10
     pollfreq = 120

would be much safer. Increasing pollfreq dramatically reduces the  
number of reports that are read from the UPS, while still allowing the  
essential ones to be read more frequently.

Are you monitoring multiple UPS devices from the same system? If so,  
post your ups.conf file here.

Best regards, Arjen

PS  Changing the value of POLLFREQ in upsmon.conf is an extremely bad  
idea. Don't even consider this.
