What command (and what procedure) to change the "max total shared memory" limit. I have used ipcs to obtain data but the shared memory limit is too high. Also possibly too high is the "max number of segments" Pls advise how to further limit. Suspected malware. Thanks. Ipcs -u max number of segments = 4096 max seg size (kbytes) = 18014398509465599 max total shared memory (kbytes) = 18446744073709551612 min seg size (bytes) = 1 No analytics, no ads, no tracking, no sharing personal data.
