I set the SHM size to 48G on my witness server (with 50GB RAM) and the server stopped to produce blocks with the following message: > 2736622ms th_a database.cpp:2596 show_free_memory ] Free memory is now 50M. Increase shared file size immediately I had to stop the node, increase the shared file size, mounted more spaced to /dev/shm. Meanwhile, I thought it would be a good idea to upgrade node from [0.19.5](https://helloacm.com/steem-blockchain-incident-of-negative-vesting-and-witness-node-updated-to-0-19-5/) to 0.19.6 using command `./run.sh install`. Also, I enabled `zram` which is to compress the RAM using LZO compression algorithm. ![image.png](https://ipfs.busy.org/ipfs/QmbTvHLt7jhbsh7WqTaignyAsgEFg1ANgNux8dvKyzQC12) ``` du -h /dev/shm/shared_memory.bin 49G /dev/shm/shared_memory.bin ``` and the uncompressed size - which is the SHM size is set to 96GB - usually this number is suggested by the following: `SIZE = 2 * RAM - SWAP` The ZRAM let your node last a bit longer with the limited RAM size - however at the cost of speed because it takes efforts for processors to zip and unzip the RAM on the fly i.e. it takes a bit longer this time (around 40 hours reindexing time). ![](https://cdn.steemitimages.com/DQmX483Qw8JXdtM6JLafWJKy5qSt1MxTd1PX6yH9ZJ11gLb/image.png) For steem re-indexing, the time required can be shortened if the CPU frequency is higher. Anyway, the node has produced two blocks since last re-enabled - everything seems good so far! Being a [steem witness](https://helloacm.com/steem-witness-replay-time-takes-longer-and-longer/) is not easy, it takes efforts to maintain your server regularly e.g. applying updates/hardforks - this requires that you monitor (that is your duty) the healthy of your witness node from time to time (I check that every day - every few hours when I am awake - on my phone) ![](https://cdn.steemitimages.com/DQmakFXb9afJdUGG8QkRnkyLvd1iuBD7uJfoL9xaNg8HcUs/image.png) *The latency is good and the witness is running smoothly* *// Reposted to: [https://helloacm.com/steem-witness-updated-to-0-19-6-and-server-using-zram/](https://helloacm.com/steem-witness-updated-to-0-19-6-and-server-using-zram/)* # If you like what I am doing ... ## Support me and my work as a witness - [witness thread](https://steemit.com/witness-category/@justyy/justyy-just-another-witness) by 1. voting me [here](https://steemconnect.com/sign/account_witness_vote?approve=1&witness=justyy), or 2. voting me as [a witness proxy](https://v2.steemconnect.com/sign/account-witness-proxy?proxy=justyy&approve=1) - let @justyy represent you.
