man page:
--log-async[=<lines>]

Enable asynchronous logging and optionally set the limit on the number of lines which will be queued by dnsmasq when writing to the syslog is slow. Dnsmasq can log asynchronously: this allows it to continue functioning without being blocked by syslog, and allows syslog to use dnsmasq for DNS queries without risking deadlock. If the queue of log-lines becomes full, dnsmasq will log the overflow, and the number of messages lost. The default queue length is 5, a sane value would be 5-25, and a maximum limit of 100 is imposed.

ivm met simpele hardware. allemaal op 100 zetten?

kwestie van
log-async=100

toevoegen in dnsmasq (en restarten)

doen?

aan dnsmasq toegevoegd, komt nu een stuk minder voor.
en op 100 gezet.

Is nog niet weg, maar enige oplossing is zwaardere hardware of lichtere syslog. Beide lijken me niet nodig voor dit probleem.
