OOM Kill occurs during loadtxoutset execution

I tried to load a snapshot using the assumeutxo feature provided in Bitcoin Core v28.0. I ran loadtxoutset during IBD after the block headers were synced.

But every time my login session gets killed after the following log:

..
2024-10-07T05:14:26Z FlushSnapshotToDisk: flushing coins cache (403 MB) started
...
2024-10-07T05:18:16Z FlushSnapshotToDisk: completed (230130.94ms)

2024-10-07T05:18:17Z FlushSnapshotToDisk: saving snapshot chainstate (45 MB) started
...
2024-10-07T05:22:01Z FlushSnapshotToDisk: completed (224537.77ms)
...

Checking the syslog, it appears that the process is being killed by oom.

Is this an issue with Bitcoin Core? and is there a way to work around this?

The snapshots are taken from the link below:

Do Kwon’s Detention Prolonged Until 2024 As Montenegro Responds To Extradition Requests

Image
According to an International Business Times report , Montenegro’s Supreme Court decided to extend the detention of TerraForm Labs founder and CEO Do Kwon until February 2024, following extradition requests from the United States and South Korea. Closed-Door Discussions Reveal Montenegro’s Plan For Do Kwon Initially set to be extradited to the US on December 15, Do Kwon’s fate turned when the Montenegrin High Court ruled to prolong his stay until February 15, 2024. The decision stems from charges related to the collapse of the TerraUSD stablecoin, which led to significant financial losses. The High Court had previously ordered Kwon’s extradition by Friday, but his defense team appealed the decision in the appellate court in Podgorica, the capital of Montenegro. The Montenegrin Court of Appeal confirmed that Kwon contested the High Court’s ruling, vehemently stating, “I do not submit to the court’s decision.” Recent reports indicate that Montenegro’s Justice Minister, Andrej Mil

Sam Bankman-Fried Trial Begins Tomorrow: 3 Reasons Ex-SEC Official Foresees Conviction

Image
The trial of Sam Bankman-Fried, the founder of cryptocurrency exchange FTX and hedge fund Alameda Research, is set to commence in New York on Tuesday, October 3.  This comes almost a year after the collapse of both FTX and Alameda Research. The events leading up to the trial paint a picture of alleged fraudulent activities and money laundering that caused significant damage to the businesses involved. Ex-SEC Official’s Bleak Prediction As Sam Bankman-Fried Trial Commences In a nutshell, Alameda Research purportedly took customer deposits from FTX and invested them in fictitious crypto tokens, which derived their value from the confidence in FTX’s operations.  When this confidence waned, FTX and Alameda Research suffered substantial losses, which many argue contributed to a broader disillusionment in the cryptocurrency industry.  Following an investigation, federal authorities uncovered numerous alleged crimes, leading to seven federal fraud and money-laundering charges against B

Ethereum Price Plummets 9% As Fed Chair Passes Hawkish Remarks

The crypto community has witnessed another price plunge after the just concluded Federal Reserve annual meeting.
