LiteSpeed + WordPress Troubleshooting – cPanel/WHM, AWS EC2 & Server Crashes

---

---

We’re looking for a server administrator or performance specialist with deep experience in LiteSpeed Web Server + WordPress, AWS EC2, and cPanel/WHM environments to help us troubleshoot a stability issue affecting several of our production servers. The Problem: I can't say for certain that the problem is LiteSpeed but after recently migrating 3 cPanel servers from Engintron to LiteSpeed we had 3 un-recoverable crashes in the past 3 weeks. By comparison, our legacy Nginx/Apache systems have had only 1 unrecoverable crash in 5 years. While WordPress performance has improved with LiteSpeed, these servers show consistently higher IO Wait than our legacy Nginx/Apache setups (even with increased IOPS). We want to determine if the issue is specifically related to LiteSpeed, the increased IO Wait, or some other configuration miss-match, and conceivably it could be simply a coincidence and it's an AWS underlying hardware problem and not at all related to LS. The oldest LS server had been running for ~6 months without any issues before it crashed twice within the span of about 1 week. Out of a total of 22 running VMs, this server has crashed twice (we've had only 1 other unrecoverable crash in 5 years). Perhaps the VM remained on the same physical host after the first crash and this is the result of degraded AWS hardware? The third unrecoverable crash was also a new LS server that had been in production for about 6 weeks before it crashed. All 3 LS servers have plenty of CPU/RAM and no other obvious bottlenecks. All three crashes required us to restore from snapshots. In 2 cases the AWS console was un-responsive, in 1 case the AWS console was responsive. In all 3 cases the VMs could not be booted. Ultimately we were able to get all 3 volumes working again; 2 recovered by simply re-attaching them to a new EC2 instance, and 1 had to have the filesystem repaired (we did not use the volumes, this was just for forensic analysis to see if we could determine why they would not boot). Even if the problem is AWS hardware related, we should have the LS and server configuration reviewed by an expert. And, we’re not AWS experts, so some of our EC2 instance and EBS configuration choices may not be optimal. We’d appreciate input on that as part of the review. Our Stack: - AWS EC2 C6a instances - gp3 disks - AlmaLinux 9 - cPanel/WHM - LiteSpeed Enterprise (with LSCache for WordPress) - Imunify360 - Cloudflare (free plan) Skills We're Looking For: - Familiarity with AWS EC2 instance types and EBS tuning - In depth experience with cPanel/WHM - Deep, practical experience with LiteSpeed Web Server - Ability to analyze server performance (IO, CPU, memory, caching, etc.) - Experience using AWS health checks, instance logs, or CloudWatch to investigate system-level issues - Experience interpreting logs and diagnosing server crashes - Experience optimizing WordPress performance in shared server environments Goals: - Expert review of configuration - LS, EC2, cPanel, EBS, etc. - Help us understand what’s really going on—what’s normal and what’s problematic, fix problems. - Recommend and, if appropriate, implement configuration changes - Help us determine if LiteSpeed is viable long-term for our workload or if we should be considering alternatives We are a small dev team managing about 20 medium-sized WordPress sites for long-term clients. This is a short-term, paid troubleshooting engagement, but there may be longer-term opportunities depending on fit and outcome. Thanks, Daniel
