Hello I would like some help setting the 'nf_conntrack_max' and 'nf_conntrack_buckets' on my system. I have checked the sources I can and everybody seems to have a different answer - some depending on 32 or 64 bit - some saying only odd numbered 'bucket' values - some saying multiply by the page size - some say divide ... My system is getting close to the 'max' and I need to increase the limit (nf_conntrack_max). I know the 'buckets' (hash) value is linked. So my question is simple - How do I calculate the values of the 'max' and 'bucket'? My current values are 131072 for 'max' and 32768 for 'buckets' (yes our application uses a lot!) What are the next values I can enter? I have the following system: Linux system-01 2.6.32-504.1.3.el6.x86_64 #1 SMP Tue Nov 11 17:57:25 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux With this much memory: MemTotal: 32848292 kB MemFree: 1206260 kB Buffers: 339644 kB Cached: 26568272 kB SwapCached: 0 kB Thanks in advance Paul ________________________________ Disclaimer: This e-mail (and any attachments to it) is confidential and intended solely for the named person/s to whom it is addressed.
